How to use the bitcore.Key function in bitcore

var server = foxtrot.createServer({key: identity});
tracer.onServer(server);
server.on('connect', function(socket) {
  socket.on('data', function(data) {
    console.log('got data from client = '+data);
    socket.write(data+' back at you!');
  });
  socket.on('close', function() {
    console.log('socket closed');
  });
});

// create a server for connecting a peer that runs on top of foxtrot
var identity = new Key();
identity.private = new Buffer('1ff8def92d1d277066063fb0680454ebfd6da1b614f57095cc4fc08034759d6f', 'hex');
identity.regenerateSync();
var server = foxtrot.createServer({key: identity});
tracer.onServer(server);
server.on('connect', function(socket) {
  foxtrot.addPeer(socket);
});

// create a server for proxying http
var identity = new Key();
identity.private = new Buffer('afc5f0040a950ad4f45792bbe13f700f698d3876af2464b4fe6e7440795de4e0', 'hex');
identity.regenerateSync();
var server = foxtrot.createServer({key: identity});
tracer.onServer(server);
server.on('connect', function(foxSocket) {
  var client = net.connect({host: '127.0.0.1', port: 1337}, function() {
